The documentary, which is scheduled to be released in August, will chronicle the rise and fall of Walker’s career and his nine-figure fortune. Walker stated that he chose to do this documentary both in order to clear the air on some aspects of his financial turmoil as well as instruct young NBA players on how to be responsible with their money.

“I think there were a lot of false things put out there and I wanted an opportunity to get my chance to tell my side of the story the correct way,” Walker said. “I just felt like I was getting misjudged in the public eye, not so much about losing money but how I lost it and what were the things that went on to lose it. More importantly, I’m trying to use it as a learning tool for younger guys that come into the NBA, but also for kids. … I think, as an NBA player, we look at ourselves as a fraternity, so I try to make sure that I can give back and really turn this negative story into a positive.”

A three-time All-Star, Walker earned $108 million in salary during his NBA career. However, a combination of poor investing ventures, gambling and unnecessary purchases, such as a $400,000 Maybach car, led to Walker filing for bankruptcy in 2010.

“It took a while for me,” Walker said. “It took 10-plus years in the league for me to start seeing a little difference in people, let alone my financial changes. I tried to take more risks, as far as investing. I started dipping and dabbing in real estate investments and making things a little bit more difficult than it had to be. I trusted people that I shouldn’t have trusted in. … I think the gambling piece got blown way out of proportion, so I wanted to bring that to light. … People got the wrong impression that I gambled my money away.”

No, seriously, Antoine Walker wants to be the next coach of the Boston Celtics.

‘I want to be back in the game, I love the game and am a student of the game,’ he told The Boston Globe. ‘I want to stress seriously that I do want to become a coach … there’s a lot of guys starting to get opportunities and so the league is getting younger coaches. Obviously I’m lacking in experience but we’ve all got to start from somewhere.’

OK, then. I guess these would be the Top 10 reasons the Celtics should hire Antoine Walker.

Former Celtic Antoine Walkerwas sentenced Tuesday by a Las Vegas court to five years of probation and ordered to pay $770,000 in gambling debts. Walker, 35, pleaded guilty in June to felony fraudulent check charges related to his failure to pay gambling debts to three casinos.

As part of a plea deal, Walker is prohibited from gambling.

A three-time All-Star with the Celtics, Walker last played in the NBA in 2008 with the Timberwolves. He has tried to make an NBA comeback since making a brief appearance in a Puerto Rican league in 2010.

In somewhat of a footnote in his most recent Sports Illustrated column, Ian Thomsen listed the records of NBA teams against oppoenents with a .500 record or better. You’ll never guess which team ranked atop the list.

Every day, people are coming up with new ways to capture how impressive the 2010-11 Celtics have been despite injuries that are piling up faster than my Christmas shopping list.

But the fact that the Celtics are 10-2 against above-.500 teams while no other Eastern Conference club has a winning record against those same squads might tell us all we need to know about the C’s chances of returning to the NBA Finals.

Against the best, the Celtics have been the best.

Only three teams in the entire league own a winning record against plus-.500 teams: the Celtics (10-2), Spurs (8-2) and Mavericks (9-3). Three others — the Thunder, Nuggets and Jazz — have .500 records against teams with winning records.

The Celtics’ biggest competitors in the East — the Heat (5-6), Magic (3-6) and Bulls (4-8) — have all been disappointing against above-.500 teams, as have the Knicks (3-5) and Hawks (2-7). In fact, 10 teams have two wins or fewer against opponents with a .500 record or better, including the Lakers, who are 1-3 in just four games against quality opponents this season.

Yesterday, the Celtics held their annual Media Day extravaganza, leading into today’s training camp kickoff. Check out the top five quotes that came out of a day that featured Shaq donning green for the first time …

Shaquille O’Nealon Kobe Bryant’s five rings: “Yeah, I heard it. My whole career I’ve been the measuring stick. Glad to see I’m still relevant. I would’ve been more upset, more hurt, if Tim Duncanwould’ve made the comment. I don’t compete with guards. They have the ball more than I do, they shoot way more than I do. You can’t compete with guards. I’m only competing with Tim Duncan, so hopefully I can get No. 5 before Tim Duncan, respectfully before Tim Duncan.”

On the bus ride down to training camp in Newport, Nate Robinson played a few pranks on his sleeping teammates–including Shaq, KG and Delonte–and he posted the pictures to prove it on his Twitter page. Funny stuff.

Antoine Walker’s unemployment

Just a fantastic piece on Antoine Walker by David Aldridge. It’s blunt. He cited one coach who called the former first-round pick “a bad guy in Boston.” Walker touched on his gambling problem and how a “terrible decision” to invest in Chicago real estate led to losses in the double-digit millions. He talked about how he’s had to shrink his inner-circle to a select few, which includes M.L. Carr. After ballooning to almost 300 pounds, Walker is back down to about 265 and looking for a job. So far, though, he’s been turned down by everybody, including the Heat, who he won a championship with in 2006.

“He is a long, long way from the Shimmy and the three All-Star appearances,” writes Aldridge, “and the days he and Paul Piercewere the Celtics’ future, and the day that he signed an extension in Boston that should have taken care of his family for life. There’s no buzz that I can detect that there’s a team interested, so Walker will wait and see if someone goes down during camp and a team needs a body. He wouldn’t mind a camp invite just so he can stay in shape, even if there’s not a real prospect of a job.

“And if it ends for him here? Well, he’s been poor before.”

Paul Pierce, the blogger

Pierce posted a blog on the Boston.com website yesterday. He described how meaningful his high school jersey retirement ceremony.

“Of all the things in my career,” he wrote, “going back to Inglewood High School and having my jersey retired this week in front of my family and friends and the people in my community who supported me from the beginning, was one of the most memorable.”

Considering his career includes an NBA title, that’s saying a lot.

Celtics Late Night Show

Listen to our own Paul Flannery on the Celtics Late Night Show by Gino’s Jungle. He touches on all things green, including Media Day, why fans will like Jermaine O’Neal, Shaq’s star quality, KG’s health, why Rajon Rondodoesn’t watch basketball and the addition of Lawrence Frankto the coaching staff.

Former Celtics forward Antoine Walker appeared in a Las Vegas court Monday and was ordered to face trial on felony bad check charges that he failed to repay almost $1 million in gambling debts to three Vegas casinos. The judge noted that Walker had yet to make any progress repaying some $770,000 he agreed to pay in restitution, court fees and penalties.

Walker filed for bankruptcy last month in Florida, and the Las Vegas prosecutor indicated that he is working with Walker’s lawyer on a deal that would avoid forcing Walker to serve jail time.
